Xanthochymol and garcinol, isoprenylated benzophenones purified from Garcinia xanthochymus fruits, showed multiple activities against fungal biofilms. Both compounds effectively prevented emergence of fungal germ tubes and were also cytostatic, with MICs of 1 to 3 ΞM. The compounds therefore inhibited development of hyphae and subsequent biofilm maturation. Xanthochymol treatment of developing and mature biofilms induced cell death. In early biofilm development, killing had the characteristics of apoptosis. These activities resulted in failure of biofilm maturation and hyphal death in mature biofilms. In mature biofilms, xanthochymol and garcinol caused the death of biofilm hyphae, with 50% effective concentrations (EC₅₀s) of 30 to 50 μM. Additionally, xanthochymol-mediated killing was complementary with fluconazole against mature biofilms, reducing the fluconazole EC₅₀ from greater than 1,024 μg per ml to 13 μg per ml.

The invention relates to the technical field of medicines, in particular to new application of theaflavin as a synergist of antifungal drugs. Through in vitro experiments, when used together with fluconazole, itraconazole, miconazole, ketoconazole and other antifungal drugs, theaflavin can increase therapeutic effect on slight surface and deep fungus infection to some extent and can restore the effect of the antifungal drugs on drug-resisting fungi. Therefore, the theaflavin can be used as the synergist of the antifungal drugs. The invention provides new application for the theaflavin; when used as the synergist of the antifungal drugs, the theaflavin not only can increase the antifungal effect of the drugs, but also can restore the effect of the antifungal drugs on the drug-resisting fungi in the condition that clinic fungal drug resistance is more and more common and drug resistance degree is more and more serious. The application dosage of the antifungal drugs can be reduced, so that medical expenses can be saved for patients, and the toxic and side effects of the drugs are reduced.
